Preferably, the top of the cutting ring is provided with internal teeth, and a locking gear is meshed with the internal teeth; the top end of the eccentric main shaft is provided with a groove matched with the anti-loosening gear, and a pressing block is tightly pressed between the anti-loosening gear and the main shaft nut.

Preferably, the thread tightening direction of the cutting ring is opposite to the rotation direction of the eccentric main shaft.

Preferably, a bottom steel ring is arranged in the pressing sleeve, the inner side of the bottom steel ring is sealed with the eccentric main shaft, and the inner side of the pressing sleeve is fixed with the outer side of the bottom steel ring in a sealing mode.

Preferably, the pressing sleeve is provided with a buckling hole matched with the mounting and dismounting tool.

Preferably, the top of the spindle nut is a wear surface, and the nut top of the bolt is lower than the top of the spindle nut.

Preferably, at least two nuts are mounted on the bottom of the bolt.

The utility model has the advantages that:

one, through set up the wear-resisting batch ring of outwards opening at main shaft nut to correspond wear-resisting batch ring and set up the reflection fill, during actual operation, the material that gets into from the feed inlet can be thrown away to the inner wall of reflection fill by rotatory wear-resisting batch ring, and gets into broken chamber after the reflection of reflection fill inner wall, makes to divide the material very even, effectively promotes crushing performance.

Second, through set up locking gear, briquetting between main shaft nut and cutting ring to and opposite screw thread design for cutting ring, broken wall are difficult not hard up in the course of the work, ensure the life of broken wall.

Detailed Description

The following description will be further made in conjunction with the accompanying drawings of the specification, so that the technical solution and the advantages of the present invention are clearer and clearer. The embodiments described below are exemplary and are intended to be illustrative of the present invention, but should not be construed as limiting the invention.

Additional aspects and advantages of the invention will be set forth in part in the description which follows, or may be learned by practice of the invention.

As shown in fig. 1, a cone crusher crushing wall fixing device is located at the top end of an eccentric main shaft 1 of a cone crusher, and comprises: the crushing device comprises a main shaft nut 2, a cutting ring 3 and a pressing sleeve 4, wherein the main shaft nut 2 and the cutting ring 3 are fixed together through a bolt 5, the cutting ring 3 is fixed with the eccentric main shaft 1 through threads, and a crushing wall 6 is pressed on a crushing cone 7 through the pressing sleeve 4; the spindle nut is characterized in that a wear-resistant batch ring 8 is formed on the periphery of the spindle nut 2, and a reflection bucket 9 is arranged corresponding to the wear-resistant batch ring 8. Like this, during actual operation, the material that gets into from the feed inlet can be thrown away to the inner wall of reflection fill 9 by rotatory wear-resisting batch ring 8 to get into broken chamber after the reflection of reflection fill 9, make to divide the material very even, effectively promote crushing performance.

In order to ensure the material distributing effect, the opening angle between the wear-resistant batch ring 8 and the spindle nut 2 is preferably not less than 30 °.
